The Census · 2026-Q4 · sp500

AI crawlers cannot reach this site. AIR-1.2 failed, so an assistant asking about this organization gets nothing from here whatever the page contains. The score beside it says how well the site is built; this says none of it is currently reachable. Both are true, and neither replaces the other — which is why the score is no longer capped to say it.

AIR-1.1 Can AI crawlers reach your site? PASS 5 pt
Why we test this

All 10 AI agents may fetch content paths.

Your robots.txt file tells crawlers what they may read. A line left behind by a previous site or a copied template can quietly shut out the assistants people now use to find you.

AIR-1.2 Does your CDN let AI crawlers through?8 of 8 AI user-agents are rejected or challenged at the edge. PROBLEM +5
What's wrong

8 of 8 AI user-agents are rejected or challenged at the edge.

Even when robots.txt says yes, a firewall or bot-protection rule can turn assistants away before they reach your pages. We sent a request as each one and recorded what came back.

AIR-1.3 Is your page readable without a security challenge?30 of 32 sampled pages return an interactive challenge (Google reCAPTCHA). PROBLEM +1
What's wrong

30 of 32 sampled pages return an interactive challenge (Google reCAPTCHA).

A CAPTCHA or bot check on an ordinary page stops an assistant at the door. These belong on forms and logins, not on pages anyone can read.

AIR-1.4 Have you stated what AI may do with your content?No Content-Signal line in robots.txt. Missing: search, ai-input, ai-train. PROBLEM +3
What's wrong

No Content-Signal line in robots.txt. Missing: search, ai-input, ai-train.

There is now a machine-readable way to say whether AI may search, quote or train on your material. Having a position — any position — is the point.

AIR-1.5 Can a person read your AI policy?robots.txt carries a 769-character comment, too thin to read as a policy statement. NEEDS WORK +0
What's half-done

robots.txt carries a 769-character comment, too thin to read as a policy statement.

A few plain sentences in robots.txt saying what you permit. Journalists and lawyers read this file, and right now most sites say nothing.

AIR-1.6 Are you allowing assistants to quote you? PASS 1 pt
Why we test this

No noarchive, nosnippet or max-snippet:0 directives found.

Some sites carry old settings that tell search engines not to show excerpts. Those same settings stop an assistant quoting your page in an answer.

AIR-1.7 Does this page declare its real address? PASS 2 pt
Why we test this

97% of sampled pages emit a valid, self-consistent canonical. 1 have problems.

A canonical link tells a machine which URL is the true one. Without it the same content can be treated as several competing pages.

AIR-1.8 Is your page structured so a machine can follow it?50% of sampled pages carry one main element, a wrapping article or section, and a nav. 15 exceed 12 divs per semantic element. NEEDS WORK +1
What's half-done

50% of sampled pages carry one main element, a wrapping article or section, and a nav. 15 exceed 12 divs per semantic element.

Meaningful sections rather than an undifferentiated wall of containers. It is the difference between a document and a soup of boxes.

AIR-1.9 Do your headings tell a clear story? PASS 2 pt
Why we test this

94% of sampled pages have exactly one non-empty h1 and no skipped heading levels. 2 have no h1

One main heading, then sub-headings in order. Assistants use headings to work out what a page is about and which part answers a question.

AIR-1.10 Do you publish a guide for AI assistants?/llms.txt lists 0 links across 4 sections, covering 0% of the sitemap. Problems: no Markdown links. PROBLEM +1
What's wrong

/llms.txt lists 0 links across 4 sections, covering 0% of the sitemap. Problems: no Markdown links.

A file at /llms.txt listing your most important pages. It is early and cheap, and it forces a useful conversation about what actually matters on your site.

AIR-1.11 Can a machine tell what your organization is?41 of 264 entity nodes carry an @id (16%). The WebPage to WebSite to Organization chain is broken at WebPage->WebSite, WebSite->Organization. PROBLEM +1
What's wrong

41 of 264 entity nodes carry an @id (16%). The WebPage to WebSite to Organization chain is broken at WebPage->WebSite, WebSite->Organization.

Structured data that links together — your organization, your site, this page — rather than a scattering of disconnected labels.

AIR-1.12 Can a machine be certain it is you?27 sameAs links: 0 tier-1 authority identifiers, 0 tier-2, 27 social. PROBLEM +1
What's wrong

27 sameAs links: 0 tier-1 authority identifiers, 0 tier-2, 27 social.

Links from your markup to authoritative records like Wikidata or ROR. Without one, an assistant is guessing which organization of your name it has found.

AIR-1.13 Can a machine find out who you are?0 of 7 organizational facts are present in the Organization markup: none. PROBLEM +2
What's wrong

0 of 7 organizational facts are present in the Organization markup: none.

Founding date, leadership, address, contact details, legal identifiers. Thin About pages are the most common weakness we see.

AIR-2.1 Primary content is present without JavaScript PASS 6 pt
Why we test this

Raw HTML contains 100% of rendered text on average across 31 URLs. The worst template is /: 100% across 2 pages. 1 URLs were excluded from the mean.

AIR-2.2 Progressive disclosure content ships in the initial HTML0 of 31 pages ship every disclosure panel populated in the raw HTML. PROBLEM +2
What's wrong

0 of 31 pages ship every disclosure panel populated in the raw HTML.

AIR-2.3 Real data tables with header cells4 tables: 0 complete, 0 without scope on header cells, 4 with no header cells, 0 used for layout. PROBLEM +1
What's wrong

4 tables: 0 complete, 0 without scope on header cells, 4 with no header cells, 0 used for layout.

AIR-2.4 Stable, human-readable anchor IDs on section headings0 of 216 subheadings carry a slug-like id (0%); 12 have generated or unstable ids. NEEDS WORK +1

About these numbers. Points are whole numbers everywhere on this page. The arithmetic behind them is not — a test scores its weight times its band divided by four, so a row can earn 1.5 points and print as 2. Scores are computed from the exact figures and rounded once, at the end, never from the rounded rows. That means adding the points column up will not give you the score exactly. The rule is published in the standard.
